xmember modification

modify cooling hoses
80e overlay in the PCM tune
modify wiring harness and add a 2nd speed sensor to the PCM and trans
custom converter or spacer, longer bolts and flat flexplate

I'm sure I forgot something. Don't think swapping to an 80e is a cheap task, it takes a bit of work and funding.

This is not needed...buy a flexpate from a 98 f-body...it's dished so it does not require a spacer and in turn does not need the longer bolts

oh and FYI 97-up 80e's are the ones that will work in the LS based trucks/motors
